What issue can occur when oven doors do not shut tightly?

When oven doors do not shut tightly, one of the primary concerns is the loss of heat, which can lead to inefficient cooking and potential safety hazards, such as gas leaks. A properly sealed oven is essential for maintaining the appropriate cooking temperature. If the door does not close completely, heat can escape, causing the oven to work harder to maintain its set temperature. This not only affects cooking times and food quality but can also result in gas being released improperly if the oven is powered by gas.

Additionally, the combination of heat loss can lead to increased gas consumption, making the appliance less efficient and potentially creating a dangerous situation if unburned gas accumulates. In summary, ensuring that the oven door is tightly sealed is crucial for safety, efficiency, and optimal cooking performance.
